The JBX42661 FC/APC to LC/UPC Duplex Singlemode Fiber Patch Cable represents the ideal solution for professional fiber optic network installations requiring reliable, high-performance connectivity between incompatible connector types. Technical Excellence: Built with 9/125 singlemode fiber conforming to G.657.A1 specifications, this 1-meter cable delivers industry-leading performance metrics. The typical insertion loss of 0.15dB and minimum return loss of 20dB ensure signal integrity across both 1310nm and 1550nm wavelengths. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm exceed standard requirements, making this cable suitable for long-distance signal transmission. Connector Compatibility: The FC/APC (ferrule ceramic/angled physical contact) to LC/UPC (subscriber connector/ultra physical contact) duplex configuration with Type A to B crossover polarity enables seamless integration between equipment using different connector standards. This cross-connector design is particularly valuable when upgrading legacy systems or integrating equipment from multiple vendors. Regulatory Compliance & Installation: TAA compliance makes this cable eligible for government and large enterprise procurements. RoHS/ELV certification ensures environmental compliance, while riser-rated (OFNR) jacketing permits installation in building plenum spaces. The compact 1.8mm outside diameter facilitates easy routing through conduit and cable trays. Performance Testing: Each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. The yellow jacket provides high visibility during installation and troubleshooting. Flexibility & Support: Custom lengths are available for unique installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty. Ideal Applications: • Data center interconnections • Telecommunications equipment upgrades • FTTH (Fiber to the Home) installations • Network backbone upgrades • Test and measurement equipment connections
